Question

Roshan purchased 10kg of rice at the rate of Rs. 15

per kg and 25kg of rice at the rate of Rs. 14per kg. He

mixed the two and sold the mixture. Approximately at

what rate per kg should he sell the mixture to make

40 %profit in the transaction?​

Answer 1

Answer:

20rs

Step-by-step explanation:

first find the total cost price at which he purchased rice so C.p.=10×15+25×14

=150+350=500rs

we must get profit 40% so

40%of 500

=40/100×500

=200

now our selling price will be

SP=500+200=700

700RS for 35 kg

so for 1 kg

SP=700/35=20

HOPE IT HELPS ☺
